A resource-efficient development of VELOX-technologies during erection and reconstruction of prefabricated monolithic floor slabs

Abstract

A resource-efficient method of installation of prefabricated monolithic floor slabs by increasing the degree of their construction readiness is proposed in the article. This effect is achieved by the reducing of their own weight and the use of fixed formwork. The reduction in the dead weight of the precast-monolithic floor slab is ensured by the use of light three dimensional lined forms of trapezoidal or rectangular shape, preferably made of expanded polystyrene during the installation of the floor slab. The use of fixed timber formwork will obviate the need for the later implementation of labor-intensive finishing and insulation works. Thus, the installed floor slab will have an increased degree of building readiness immediately after its manufacture, and will also reduce the weight of the structure, which in turn will reduce the material consumption and accordingly the cost of the supporting structures of the building.

Improving the manufacturability of floor slabs by pre-installing elements that partially replace reinforced concrete and formwork

“…This is ensured by a pre-fabricated hermetically sealed continuous permanent formwork. The proposed clamps simultaneously play the role of rigid connections of individual shields into a geometrically stable and unchangeable system [21]. Thus, the arranged structure of the precast-monolithic floor slab will have an increased degree of construction readiness immediately after its manufacture in one complex constructiontechnological process.…”
